6adba43fd2 Input: synaptics-rmi4 - add support for F55 sensor tuning
Sensor tuning support is needed to determine the number of enabled
tx and rx electrodes for use in F54 functions.

The number of enabled electrodes is not identical to the total number
of electrodes as reported with F55:Query0 and F55:Query1. It has to be
calculated by analyzing F55:Ctrl1 (sensor receiver assignment) and
F55:Ctrl2 (sensor transmitter assignment).

Support for additional sensor tuning functions may be added later.

a94e502c22 cpuidle: dt: assign ->enter_freeze to same as ->enter callback function
enter_freeze() callback is expected atleast to do the same as enter()
but it has to guarantee that interrupts aren't enabled at any point
in its execution, as the tick is frozen.

CPUs execute ->enter_freeze with the local tick or entire timekeeping
suspended, so it must not re-enable interrupts at any point (even
temporarily) or attempt to change states of clock event devices.

It will be called when the system goes to suspend-to-idle and will
reduce power usage because CPUs won't be awaken for unnecessary IRQs
(i.e. woken up only on IRQs from "wakeup sources")

We can reuse the same code for both the enter() and enter_freeze()
callbacks as along as they don't re-enable interrupts. Only "coupled"
cpuidle mechanism enables interrupts and doing that with timekeeping
suspended is generally not safe.

Since this generic DT based idle driver doesn't support "coupled"
states, it is safe to assume that the interrupts are not re-enabled.

This patch assign enter_freeze to same as enter callback function which
helps to save power without any intermittent spurious wakeups from
suspend-to-idle.

9d66195807 powerpc/64: Provide functions for accessing POWER9 partition table
POWER9 requires the host to set up a partition table, which is a
table in memory indexed by logical partition ID (LPID) which
contains the pointers to page tables and process tables for the
host and each guest.

This factors out the initialization of the partition table into
a single function.  This code was previously duplicated between
hash_utils_64.c and pgtable-radix.c.

This provides a function for setting a partition table entry,
which is used in early MMU initialization, and will be used by
KVM whenever a guest is created.  This function includes a tlbie
instruction which will flush all TLB entries for the LPID and
all caches of the partition table entry for the LPID, across the
system.

This also moves a call to memblock_set_current_limit(), which was
in radix_init_partition_table(), but has nothing to do with the
partition table.  By analogy with the similar code for hash, the
call gets moved to near the end of radix__early_init_mmu().  It
now gets called when running as a guest, whereas previously it
would only be called if the kernel is running as the host.

7d43640022 tracing: Add error checks to creation of event files
The creation of the set_event_pid file was assigned to a variable "entry"
but that variable was never used. Ideally, it should be used to check if the
file was created and warn if it was not.

The files header_page, header_event should also be checked and a warning if
they fail to be created.

The "enable" file was moved up, as it is a more crucial file to have and a
hard failure (return -ENOMEM) should be returned if it is not created.

9287aed2ad selinux: Convert isec->lock into a spinlock
Convert isec->lock from a mutex into a spinlock.  Instead of holding
the lock while sleeping in inode_doinit_with_dentry, set
isec->initialized to LABEL_PENDING and release the lock.  Then, when
the sid has been determined, re-acquire the lock.  If isec->initialized
is still set to LABEL_PENDING, set isec->sid; otherwise, the sid has
been set by another task (LABEL_INITIALIZED) or invalidated
(LABEL_INVALID) in the meantime.

This fixes a deadlock on gfs2 where

 * one task is in inode_doinit_with_dentry -> gfs2_getxattr, holds
   isec->lock, and tries to acquire the inode's glock, and

 * another task is in do_xmote -> inode_go_inval ->
   selinux_inode_invalidate_secctx, holds the inode's glock, and
   tries to acquire isec->lock.

478409dd68 tracing: Add hook to function tracing for other subsystems to use
Currently Function traces can be only exported to the ring buffer. This
adds a trace_export concept which can process traces and export
them to a registered destination as an addition to the current
one that outputs to Ftrace - i.e. ring buffer.

In this way, if we want function traces to be sent to other destinations
rather than only to the ring buffer, we just need to register a new
trace_export and implement its own .write() function for writing traces to
storage.

With this patch, only function tracing (trace type is TRACE_FN)
is supported.

invoked function with interrupts disabled, but this calling convention is
not preserved as the MSR is not modified by anything else than this code.

Since commit 1cf4f629d9 ("cpu/hotplug: Move online calls to

the CPU_DOWN_FAILED notifier also runs on the hot plugged CPU.

disabled. This calling convention is preserved.

7ff723ad0f scsi: mpt3sas: Unblock device after controller reset
While issuing any ATA passthrough command to firmware the driver will
block the device. But it will unblock the device only if the I/O
completes through the ISR path. If a controller reset occurs before
command completion the device will remain in blocked state.

Make sure we unblock the device following a controller reset if an ATA
passthrough command was queued.

7630b3a599 scsi: hpsa: use bus '3' for legacy HBA devices
Older controllers use SCSI target id '0' for the first internal disk. As
the controllers are now placed on the same bus as the internal disks
this leads to a clash with the SCSI target id of controller.  This patch
checks the SCSI revision, and moves older controller to bus '3' to be
compatible with older releases and avoid this problem.

Pull thermal management fix from Zhang Rui:
 "We only have one urgent fix this time.

  Commit 3105f234e0 ("thermal/powerclamp: correct cpu support check"),
  which is shipped in 4.9-rc3, fixed a problem introduced by commit
  b721ca0d19 ("thermal/powerclamp: remove cpu whitelist").

  But unfortunately, it broke intel_powerclamp driver module auto-
  loading at the same time. Thus we need this change to add back module
  auto-loading for 4.9"

39385cb5f3 Bluetooth: Fix using the correct source address type
The hci_get_route() API is used to look up local HCI devices, however
so far it has been incapable of dealing with anything else than the
public address of HCI devices. This completely breaks with LE-only HCI
devices that do not come with a public address, but use a static
random address instead.

This patch exteds the hci_get_route() API with a src_type parameter
that's used for comparing with the right address of each HCI device.

b66c08ba28 SCSI fixes on 20161121
Two small fixes.  One prevents timeouts on mpt3sas when trying to use
 the secure erase protocol which causes the erase protocol to be
 aborted.  The second is a regression in a prior fix which causes all
 commands to abort during PCI extended error recovery, which is
 incorrect because PCI EEH is independent from what's happening on the
 FC transport.

d55b352b01 NFSv4.x: hide array-bounds warning
A correct bugfix introduced a harmless warning that shows up with gcc-7:

fs/nfs/callback.c: In function 'nfs_callback_up':
fs/nfs/callback.c:214:14: error: array subscript is outside array bounds [-Werror=array-bounds]

What happens here is that the 'minorversion == 0' check tells the
compiler that we assume minorversion can be something other than 0,
but when CONFIG_NFS_V4_1 is disabled that would be invalid and
result in an out-of-bounds access.

The added check for IS_ENABLED(CONFIG_NFS_V4_1) tells gcc that this
really can't happen, which makes the code slightly smaller and also
avoids the warning.

The bugfix that introduced the warning is marked for stable backports,
we want this one backported to the same releases.
